Product Description:
The PMB31D-20100-01 Brushless Servo Motor is built by Pacific Scientific with a locked-up current of 5.1 Arms to ensure consistent torque delivery. With a 240V AC supply, this servo motor delivers a nominal torque of 1.62 Nm for efficient and reliable output.
This servo motor delivers a maximum torque output of 6.26 Nm to handle excessive load demands and spikes of maximum torque in short bursts. The 8-pole rotor design of this motor enhances torque development at lower speeds while delivering smooth rotational motion for precision-based automation. The PMB31D-20100-01 brushless servo motor has a nominal speed of 6000 rpm to support high-speed operation and fast positioning. This motor’s 5.2 mH inductance rating guarantees stable current regulation, leading to accurate control and seamless torque output transitions. While operating at maximum torque, this servo motor consumes 15.3 Arms of current to deliver robust acceleration capability under high-load and dynamic operating situations. Its coefficient of electromotive force of 0.25 VRMS/rad/sec enables precise speed control and compatibility with a broad range of servo drive systems.
Constructed with NEMA size 34 specifications, the housing of this motor provides mechanical compatibility with standardized industrial mounting geometries and machine frames. Its square key output shaft facilitates reliable torque transfer to mounted components, which reduces slippage during high-speed or high-load operations. This brushless servo motor can be installed at altitudes up to 1000 meters above sea level, thus it can perform consistently in different operating locations. This brushless servo motor’s 28-minute thermal response time ensures stable temperatures under prolonged workload conditions and enhances operational reliability. The resolver feedback system of the PMB31D-20100-01 brushless motor offers accurate positional data. This feedback also maintains its performance level even in environments with electrical noise interference.
